Etymology: Belonepterygion: Greek, belone = needle; any fish with sharp pointed snout + Greek, pterygion, diminutive of pteryx = fin (Ref. 45335). More on author: Ogilby.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 0 - 10 m (Ref. 90102). Temperate; 30°N - 32°S, 120°E - 169°E
Western Pacific: Japan south to Australia; east to New Caledonia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.0 cm TL male/unsexed; (Ref. 48635)
(total): 17 - 20;
soft rays: 3 - 5. Similar to A. hiatti but differs by having a lateral line in 3 parts, more lateral scale rows (35-36 versus 28-30), and no spines in the operculum.
Found in tidal pools around coral reefs and lagoons (Ref. 559). Benthic (Ref. 75154). Eggs are guarded by the male parent (Ref. 205). Solitary, secretive crevice dweller (Ref 90102).
